I bought a pounce, and HATE it, and don't use it. I have the purple disapearing and the blue washout pens, cheap ones from Walmart and have used them a lot, and no problems. They are what I use most. I also have the little plastic chalk markers (Fons & Porter?) that have a roller tip that I've used on darker fabrics that the blue and purple won't show up on. I also have a spray that sprays white stuff that I use with plastic templates, and it washes off with a wet washcloth. I think I got it at either Walmart or a quilt shop.
